Abstract
A method and system for edge-forming cellulose products from an air-formed cellulose blank structure. The system comprises a first mould part having an edge-forming device with a protruding element configured for compacting and separating fibres of the cellulose blank structure and a second mould part arranged for cooperating with each other. The edge-forming device is movably arranged in relation to a base structure of the first mould part, and is adapted for interacting with a pressure member arranged in the base structure. The method includes the steps: providing the air-formed cellulose blank structure, and forming a compacted edge structure of the cellulose products by separating fibres of the cellulose blank structure with the protruding element, applying an edge-forming temperature, and compacting the cellulose blank structure by applying an edge-forming pressure onto the cellulose blank structure between the protruding element and the second mould part.
